Application filed April 22 1907 Serial No. 369.550.

State of Michigan, have invented certain new and useful Improvements in'Traveling-Cyb inder WebPrinting Presses; and I hereby declare that thefollowing is afu'll, clear, and exact description. thereof, referencebeing had to the accompanying drawings, which form part of thisspecification. Y

This invention is an improvement in traveling cylinder web printingpresses of the wellknown duplex type, although applicable to other kindsof presses. to enable two webs to be fed through the printing mechanismsat different speeds, so that both webs may be printed from differentforms by the same printing couples, different lengths of each web beingprinted at each operation of the press, and each web being fed throughthe press at a predetermined speed and thereafter the products of thetwo webs can be assembled together. As applied to' presses. of theduplex type, for example, if the cylinders have a travel suflicient tocover two forms arranged one after the other upon the bed, impressionscan be taken from both forms on one web and impression can be taken onthe other web from a single form placed on the same bed. Thus eight ortwelve pages could be printed simultaneously on one web by using a,double set of forms on each bed, and at the same timeaccording to therapidity of its feed. In carrying out this feature of the invention Ipreferably make the web-feeding and'deivering cylinders in two sectionsand provide gearing whereby the .shorter sections of the cylinderswhich. handle the narrow webs can be run at lower s eedthan the longersections thereof Whic handle the wide web, so that the narrow web can befed at the desired slow speed relative to the wide web. I also providenovel loo ing mechanisms whereby each web will e looped at the propertimes, in accordance with its rate of its object is.

adapted the narrow web for exfeed and delivery, am le beinglooped onlyhalf as fast and to half the extent of the wide webyand preferably bothsaid looping mechanisms are controlled by a single cam in'thisinvention.

-By-lengthening the throw or travel of the cylinders of anordinary8-page duplex press I amenabled to print 2, 4, '6, 8, 12 or 16 pa esthereon on a single web, using a-full wi th web and double set of formson each bed when printing-16 pages, and a narrower web and doublearrangement of forms when printing 8 or 12 pages; and when it is desiredto print 10 or 14 pages I use a wide web and double set of forms toprint 8 or 12 pages,

and a second narrow web and single forms on each bed,

and assemble the resultant product of the narrowweb with the product ofthe wider web of the folder.

I will now describe the invention with reference to the machineillustrated in the accompanying drawing, in which- Figure 1 representsdiagrammatically a duplex press equipped with my novel feeding anddelivering mechanisms, whereby two websmay be fed through the press atdifferent speeds. Fig. 2 is a detail sectional view illustrating theconstruction andmode of gearing the sectional feedin and deliveringcylinders, whereby two' we s may be fed through the press at differentspeeds. Fig. 3 is a detail View of the Web looping devices. Figs. a and5 are detail-views illustrating the arrangement of forms for printing aten-page and fourteen-page paper.

in the drawings 1 and to carrytwo rows of type forms, as

indicated in Figs. 4 and 5. 1 and 2 are the cylinders, co-acting withtheforms on said beds, which may be mounted in sliding carriers 3 andreciprocated back and forth of the bed by means of connecting rods 3operated by crank wheels 3*, as in the duplex? press. The beds andcylinders are preferably arranged "as in the ordinary duplex press andrequire no detailed description herein as the construction is'wellunderstood. I

Thefeeding-in devices 4 and delivery devices 5 are arranged substantiallas in the duplex press, and the guides and .ooping devices tor handlinthe main web are ar ranged; substantial as in the duplex press and needno detailed description; but will bereadily v, understood by followingthe 2 are type beds bed 2 thence over guide 63 to guide 6 then .downunder looping roller 6", then up over guide 6 to the delivery rolls 5.The guides 6 6, 6 6*, aremounted on the cylinder carriers and travelwith the cylinders. The looping rollers 6 and 6 are mounted in areciprocating frame 8, which is operated by means of a link 8 connectedto a lever 8 which is vibrated by means of cam 8, as in the duplexpress; the parts being operated in such manner that during thetaking ofan impression, while the cylinders 1 2 are rolling over the type forms,the web fed in by the feeding rollers is taken up by the ascent oflooping roller 6 while a like amount of web is given out by the ascentof the looping roller 6", so that the in-feed and out-feed of the web iscontinuous, as in the duplex press, and between impressions the loopingrollers are lowered so that the loop of web formed over 6 looping roller6" and enough of the web is shifted forward between the beds andcylinders to bring unprinted portions of the web into position to beprinted at the next movement of the clyinders over the fornr The web to,which I will call the slow web,

, is guided similarly through the press but is operated at say half thespeed bf web N.

In order to feed and deliver this web w at half speed 1 preferably makethe feed and delivery rollers 4: and 5 in sections, as indicated in Fig2 the fast section 4" of roll a is fixed to the shafts which is drivenby a suitable train of gears 4 from the drive shaft at the proper speedto feed the web VJ into the press at the desired speed.

The slow section 4 of the feed roll 4- is rotatably mounted on shaft 4and is driven, at

say half the speed of section 4", by means of the pinion al on section.4 meshing witha pinion 41 on the stub shaft 4 journaled in the frameand-carrying a 4S meshing with a gear 4 keyed on the shaft 4*, so thatthe slow section 4- is driven from shaft 4* at a. much slower rate thansection. a The delivery roll 5 is similarly constructed with fast andslow sections 5, 5 which are driven at the same s eed as the sections4*, l", of the iii-feed ro by means of trains of gears 4 and 4", asindicated in Fig.

By properly proportioning diameters of gears 4 i any desired diifen encebetween theperipheral speeds of sections 4*, 4-, can be obtained;

is transferred to the web. This will be readily unde reference to Figs.1 and 5.

or the draw-- or varying the and where a l narrow web w.

full width web is to be printed, the sections may be driven at the sames eedby substi tuting suitably proportioned gears P, 4

Assuming'that t'wo webs are to be printed, and that the slow sections 4,5- are geared at half the speed of the fast sections 4, 5*, so

as to feed the narrow slow web 11) one-half as fast as the wide fast webW, it is necessary to provide means for looping the web w in accordancewith its slower iii-feed and dc livery. A very simple and effectiveway-of looping this web is indicated inthe drawin s. As shown, the Web wpasses fronra roll uncl er suitable guides over the slow in-feed'section4 and thence under a iixed guide 7 over a looping roller 7", down underguide 7, and thence over the guide 6 beside and along with the wide webW between the beds and cylinders and as far as guide 6 then the narrowweb to passes over a guide 7, down under a looping roller 7', up over aguide 7 to the slow feed section 5 of the delivery mechanism. Thelooping rollers 7 and 7' are mounted ina frame 9, which is pivotallygears for the I connected at 9 d to ,a lever 9, which is pivoted at 9 toa fixed point of the frame and its forward free end is pivoted to theframe 8, as shown. The ivot 9 is midwaybetween the pivots 9. an '9 andtherefore the frame 9 will be moved by and with the frame 8 but willonly move half the distance traveled by frame 8, consequently the looing rollers 7 7 will only move half the distance of the looping rollers6", 6 and at half the s eed of the latter, and thus the web w will becoped exactly in accordance with its feed and'delivery, and the one setof looping cams 8 Willi care for both sets of loopers.

From the foregoing it' will be obvious that 'each web will be fedthrough the press and looped and delivered at the desired speed and inthe desired time, and that both webs are practically guided through thepress between the beds and cylinders from the guide (5? to y the guide 6in exactly the same path and by the same means, so that the cylinderswill. present both Webs to the forms simultaneously and take impressionsupon bothwcbs simultaneously. But, as the narrow web w is fed'moreslowly than the fast web W, the forms must be differently arranged andtherefore the forms from which the impressions are to be taken on thenarrow web must be only half the length. of the forms on whicn theimpressions are tobe taken on the wide cod by in g. i the forms 1,3,5,7, are arranged in tYii 'ows upon the bed i and similarly forms 3 4,6, 8, are

arranged in two rows upon the l) 1,22, so that itepages will be printedupon t wide web /V while sin le forms and placed upon the beds l and 2to be p on the This arrangement will give scribed herein.

tions 4 5 will be driven at a 10-page paper with 5 forms on each bed. Toprinta 14 page paper the forms can be arranged. as in Fig. 5, whichshows two rows of forms on beds 1, 2, to be impressed upon the wide webgiving '12 pages; while single forms 13, 14, on the beds 1, 2,.will beimpressed ,upon the narrow Web.

The arrangement of forms for printing any is led through the press like.web Wabove described, and the looping rollers 7", 7

' will not be used.

- rollers 6 6, will --slow or fast spee By the means claim as new and Ifit be desired to :handle a wide web through the press at slow speed, itwill only be necessary to alter the gearing so as to drive both sectionsat-the slow speed. Or if desired in order to drive sections 4, 5, atslow speed, like sections 4 5, the sections 4*, 5, can-be unlocked fromits shaft 4 by.

withdrawing the keys 4, and'locked to seetions'fA; and 5 in any desiredmanner, as for instance by a screw 4 engaging a shoulder 4 on section 4as' indicated in. dotted lines in Fig. 2. larly constructed. This beingmerely'a matter of mechanical selection and skill I do-not wish to berestricted to any particular construction whereby the two sections ofroll 4 and 5 may bedriven alike, at either fast or slow speed. When thesections are driven alike at slow speed, a wide web can be ledthrough'the presslike web w and looping not be used. Thus I can runthrough this ress a single wide web at or two narrow webs at differentspeeds.

described I am enabled to print any number of pages desired up to 16 bymeans of a two bed and cylinder press with a very slight additionmembers in the ordinary S-page du press, and without any material comptions in the mechanism thereof. I
